fication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements incotton-picking machines, and has for its object to construct acotton-picker that will eflectuallv ick and deposit the cotton from theen 0 ls into a suitable receptacle and wi I perform the above operation.without injuring the green bol s. blooms, orstalks of the cotton-plants.

A further object of the invention is to construct a ,c'ottonickingmachine that can be readily and easil; adjusted to conform to the heightof-the cotton-plants and that will be of the lower carrier-arms.

provided with a series of picker-fingers to engage the open bolls andremo've t e cotton therefrom and a novel construction to remove thecotton from the fin ers and deposit same in the receptacle provi edtherefor.

The invention finally consists in the novel construction, combination,and arrangement of parts throughout to be hereinafter more specificallydescribed, and particularly pointed out in the claims.

By referring to Fig. 4 of the drawings it will be observed that thearrangement of the lug f u on the arm (I is such that it will engage theu c" from a different position from that of the 11g 6' of the arm (1. Bythis arrargeincnt the carrier is turned one-half revolution to bring thecogs of the carriers into e11gagcmcnt again with the segmental toothedportion of the arms for rocking the carriers. This arrai gemcnt alsorevents the carriers from turI irg freely. 0th the upper and lower armsare secured to the carriers by a fulcrum-hearit gf (see Fi 17,) havi'. ga shaft portio'. if provided wit 1 an exterior air- Llllitl groove fwhich receives a pitrj, assing throu h the end of the carrier and 00ki:g the fu crum-bearin The arms d and d are pivotally secure to thisfulcrum-bearing. On'the carriers e e is secured a series ofpicker-fingers f provided with projecting pouts g g, cxtendirg inlongitudinal alinement with the firgers. These fingers f are arrarged ata slight incline and are provided with bevel gear-wheels g g, resting'onwashers or bushings 9 said Wheelsengaging in the secured to the frameoflthe machine- In which may be employed in lieu of the bevelg'ears g,the cogs of the racks g of course in this corstruction bei g dispensedwith r 1',

The front part of the machine is supported screw-threaded shaft-h,operating atjts lower 1 end in the block it, secured to the pgat'eh andI provided on its upper end with 'a' eye] gearwheel h", adapted to meshwith a'g ar wheel I secured on the shaft, whichis s'lipported by a braceh", fastened to the upper brace g", said shaft. being adapted to receiveja erank shaft h and adjust the forward end bfthe frame, as may hedesired, either upward or downward.

ing sheeting or casing 11 with the smaller end toward the rear of the"machine, forming a guide to carry the plants to the fingers. Arrangedwithin the wheels 6 b is an ordinary clutch-gear 11, having anoperating'handle 10, employed for engaging and disengaging thebevel-gear a, and a to impart motion to the mechanism and discontinuethe same. This clutch-gear may be arranged with its operating-handlepasslng to an suitable point on the machine that will be convenient tooperate the same. At the rear of the machine the frame portion isconstructed with an n wardly-extending yoke 1c, which is of sell cientheight to allow the arms to clear the some, said yoke being rigidlysupported by hraccs 7: k, secured to the upright standards of the frameportion, this construction serv- On the underneath side 0 the toothedracks g, at. the forward end of each, is secured a spring is, (see Fig.23 having a downwardlv-proj ectin tooth k, which engages the bevel-gear9' an assists the same into an engagement with the teeth of, the rack byturning the wheel into such a position that its teeth are ready to emgage with the teeth of the rack. The ends of the carriers are providedwith a hole 1:, (see Fig. 17,) which is adapted to receive the shaft InFig. 2l,whiol1 is a modifies tion, as be I ear-wheel l is employed tomesh with a hevelear 3*, that will be mounted on the shaft b in lieu ofthe norm 6 and screw a, as shown and described throughout thespecification. The wheel 5 secured on the shaft 0, is provided on oneside with a series of beveled teeth 1, which are ndaptedlo engage thelower carrier-arms (1" and assist the some on the slide 'i.

f '0 will now assume that all the parts have lioon secured in theirrespective positions and the machine proper is in motion without thedifferent parts heing'in operation.

The clutch is thrown in engagement, causing the hovel-gear o to engagewith the bevelgoal a, and as the machine moves forward the shaft a willbe rotated causing the wormscrew of to engage in the worm-wheel b andcommunicate motion to the vertical shafts b, causing same to revolve androtate the arms carrying the picker-linger carriers. As these carriersrevolve the wheels g y will engage in the toothed racks g" as they passbetween the curved guides, (shown more especialiy'in Fig. 25,) and thisin turn communicates motion to the picker-lingm's, causing; the same torevolve simult sineously. The machine isdrawn across the field with thesome straddle of a row of plants, so as to bring the plants within the Ushaped casing 11", thus bringing the open bolls in direct ontaot withthe wicker-lingors, which engage in the said hols and by reason of theprojecting points wind the cotton on the lingers as they are revolvedand carry the same around to the comb, the fingers of which, by reasonof the incline in the picker-fingers, will engage the said pickerfingersat the rear, and as they continue to rotate and descend on theirmovement, keeping the picker-fingers and comb-fingers in contact untilpast engagement, the cornbfingers will thus be permitted to effectuallystrip the cotton from the picker-fin ers and allow the cotton to fallinto a snitab e receptacle provided therefor.

During the time that the bevel gear-wheels g are in engagement with thetoothed racks g the teeth 2 of the lower arms, the teeth f of the upperarms will be in engagement with the teeth a serving to rock thecarriers, the picker-fingers retaining an inclined position ,throughoutthe length of the cog-racks g,

of the drawings by dotted lines. At the time that the bevel-wheels 9'leave the racks g the respectively, have passed the point of contactwith the teeth e and the lug eand of the arms come in engagement with te lugs r ")f the carriers and operate the carriers, so as to throw thefree ends of the picker-finers toward the drive-shaft b toward the rentof the machine, which position they retain until the bevel gear-wheelsof the fin ers again come in contact with the racks, w ien they will bereversed to the former position to again engage the cotton by reason ofthe teeth hein in engagement again. As the Zbevehwhee s on thepicker-fingers are about to enter the toothed racks the spring k engagesthe bevel gear-wheel before it reaches the teeth of the rack,compressing this spring, and as its tooth Z-r" passes out of'ongagementwith the bevel-gear g the action of the spring in returning to itsnormal position ro tatcs the picker-fingers and forces the bevelwheelmore readily into engagement with the teeth of the rack and prevents anylost motion at this point. As the bevel-gears g g enter into engagementwith the tooth-racks the picker-fingers will he revolved and will )eentered into the hells in an inclined position, thereby causing theprojecting points g, g of the iingersto more readily engage the cottonand to effectively remove the same from the bolls.
